New to codeigniter, actually have to use it for this project.

Ok, I’m working with a situation where there will be dynamic number of input fields in a form so i need to use $_POST to iterate thru them

//Set post arg to vars
foreach ($_POST as $name=>$values) {
    $this->global_class->checkArgFiltered($name);
    echo "{$name} = {$value}";            
}

my form action is

<form action="<?php $_SERVER['SERVER_NAME'];?>/index.php/pdf/write" method="POST" enctype="text/plain">

I need $_POST to work or I need a codeignter method.

i tried calling $this->input->post() with out param hoping that it would return an array of the post args

Please help!

So just iterate over $_POST like in your first example. What’s wrong with that?

to itterate what Colin has said.. here is an example test controller (which I have tested):

<?php
class Test extends Controller {

  function Test()
  {
    parent::Controller();
  }
  function index()
  {
    // should load a view but for demonstration purposes
    echo ("<FORM action='".site_url()."/test/res' method='post'>
           <INPUT type='TEXT' name='testp'><input type='submit'></FORM>");
  }
  function res()
  {
    print_r($_POST);
  }
}
?>

result after submitting form

Array ( [testp] => datatypedin )

And if you want the added security of the input class, do this:

foreach($_POST as $key => $value)
{
     $post_array[$key] = $this->input->post($key);

     //optional 2nd parameter of post() method runs xss filter if set to TRUE
     // e.g. $this->input->post($key, TRUE);
}

P.S. “Having” to use CodeIgniter is not a punishment, it’s a privilege wink

Then there must be another problem with your code. You probably need to show more code.

first off, thanks for the responses.


Controller

class Pdf extends Controller {

    function Pdf()
    {
        parent::Controller();    
    }
    
    //the index function is what is called first on instantiation
    function index()
    {
    }
    
    function read() {
        $this->load->library('global_class');
        $this->load->database();
        $this->load->view('pdf_read');
    }
    
    function write() {
        $this->load->library('global_class');
        $this->load->database();
        $this->load->view('pdf_write');
    }

    function form() {
        $this->load->library('global_class');
        $this->load->database();
        $this->load->view('pdf_form');
    }
    
    
}


pdf_form.php produces a basic form (for now)

<form action="/index.php/pdf/write" method="POST" enctype="text/plain">
<input type="hidden" name="filename" value="base_form_4"/>  
<hr>78 - (Text1) - Tx  - (test1)<br>Text1: <input type="text" name="Text1" value="test1"><br><hr>81 - (CheckBox1) - Btn  - Yes<br>CheckBox1: <input type="checkbox" name="CheckBox1" value="Yes" checked> Yes<br><hr>83 - (RadioButton1) - Btn  - Yes<br>RadioButton1: <input type="radio" name="RadioButton1" value="Yes" checked> Yes<br><hr>84 - (RadioButton1) - Btn  - Yes<br>RadioButton1: <input type="radio" name="RadioButton1" value="No"> No<br><hr>85 - (ComboBox1) - Ch [[(1)(item 1)][(2)(item 2)]] / 1,item 1|2,item 2 - (2)<br>ComboBox1: <select name="ComboBox1" size="1" >

<option value="1">item 1</option>
<option value="2" selected>item 2</option>
</select>
<br><hr>86 - (Button1) - Btn  - <br>Button1: <input type="checkbox" name="Button1" value="No"> No<br><hr>87 - (Text2) - Tx  - (test6)<br>Text2: <input type="text" name="Text2" value="test6"><br><hr>88 - (ListBox1) - Ch [[(1)(List 1)][(2)(List 2)]] / 1,List 1|2,List 2 - (2)<br>ListBox1: <select name="ListBox1" size="5" >
<option value="1">List 1</option>
<option value="2" selected>List 2</option>

</select>
<br><hr>
<input type="submit" name="submit" value="Post Values and Write new PDF"/>  
</form>

This form is to post to the write function which calls pdf_write.php

at the top of pdf_write.php is the code to iterate through the $_POST array

but it is empty

Can you ensure that you’re ‘POST’-ing to the correct location?

I went back to verify the posting thru Zend debug trace and in watching the vars I saw the $HTTP_RAW_POST_DATA was getting set, but $_POST was still empty, that prompted my memory, that this code be an encoding issue.
and sure enough it was.

I use zend to quick enter html so it created

<form action="/index.php/pdf/write" method="POST" enctype="text/plain">

note the enctype…

I changed it to:
ENCTYPE=“multipart/form-data”

and bamo, I get $_POST data.

Sorry for wasting your time, thx for the help

You need not set the enctype unless you’re uploading.

I actually copied and pasted that Test controller, and I also am not receiving anything from the print_r($_POST) statement.  I’ve tried it on a couple of projects on my local dev, no luck.

Perhaps an Apache configuration issue, though it’s pretty standard setup (just virtual hosts configured and entries in the /etc/hosts file as needed)?

Cheers,
Brian

I’m wondering if this might be related to the uri_protocol at all. Can you call on any of your controller methods (other than index) directly from the address bar?

It might also be worth validating your HTML.

Yes, other functions can be accessed using direct urls from the address bar no problem…

It’s a pretty standard 1.7.1 installation, a previous 1.6 installation with the above controller works fine.  Could certainly be a config parameter.  Currently the uri protocol is:

$config[‘uri_protocol’]  = “REQUEST_URI”;

Tried AUTO and others and no effect, though I cannot think of what would be stripping out the POST values completely?

I’d suggest going back to basics, and just creating a simple script outside of PHP which will allow you to submit a post value, and then read it back to you. I suspect this will work, in which case, the problem is CodeIgniter (which I doubt), or that your HTML is not valid. Have you tried getting this to work with different browsers?
